SPECIFICATION forming part of Letters Patent No. 601,456, dated March 293 1898. Application filed July 16, 1897. Serial No. 644,856. (No model.)

To all whom it may concern:

Be it known that I, EUGENE P, WOILLARD,

- a citizen of the United States, residing at Sugden,in the county of Dade and State of Florida,

have invented a certain new and useful Improvement in Gas-Pressure Generators, of which the following is a specification.

My invention relates especially to pressuregenerators of the contin.nous-combustion type, whereby a greater amount of heat is saved and converted into a useful working pressure than has hitherto been possible.

The objects in view areto provide a simple ane instantaneous internal-combustion pressure-generator where gas or oil-vapors or other like rapid combustibles are burned in the retort or combustion-chamber with the proper amount of air to form perfect combustion.

The burned gases thus formed pass outof` the combustion-chamber, Where they unite or eommingle with steam that has been generated in the coils that surround the inner walls of', the combustion-chamber and pass from the combination to the mixing chamber. The steam issues from said pipes as saturated steam and, commingling with theburned gases, forms superheated steam, which is used eXpansively erbotherwise in any desirable form of engine, whether it be areciprocating, oscillating, rotary, or steam turbine, but preferably in the latter.

A further object of the invention is to provide an elastic motive fluid having the advantage of both gas and hot air and also steam without their disadvantages-Daniely, the tendencyvwhich gas and hot air have to destroy the sensitive parts of an engine and also the rapid falling oil' of the pressure-since by the addition of steam the expansive qualities are prolonged and act more as a lubricant than as a destroyer of the lubricatingagent.

Further objects and advantages of my iinprovement will appear in the following jdescription, and the novel fea-tures will be particularly pointed out in lthe claims.

In the drawings, Figure l isa vertical section of my improvement in its preferred form,

' showing plainly the construction thereofgllig.

2, a side elevation in diagrann-showing hcw my improvement is to be applied', and Fig.

3 is an enlarged view ofthe electric ighiter.

Similar letters and numerals i" reference inner Walls of said chamber until it reaches the crown-sheet C, where it also lines the same bybeing properly coiled, leaving an aperture in the center thereof, so as to obstruct the passage 2. From thence said pipe 4,-after lining all the inner walls or surfaces of the combustion-chamber,v continues to make a series of flat coils 6,that are suspended Within the upper portion of the chamber l, and

finally said coils end by turning up and-passing through the central passage of the flat coils 6 and through the neck 2 into the lower end of the mixing-chamber 3, being held in position by a suitable bracket 7 ,throu gh which it passes, and is secured by a nut 8. The bottom of the mixing-chamber 3 is made Within a convex head, consisting of the crown-sheet C, in order that the Water of condensation may be drained therefrom by the cock 9.

The object of providing the two chambers 1 and 3 with aiared-neck tube between them is to keep the combustion-chamber l clear of any steam or moisture, so that only pure air is present to form perfect combustion in combination with the gas or oil-vapors. After the products of combustion havepassed through the neck 2 into the mixing-chamber 3 and Through y have lcommingled 'with the steam issuing through the nozzle l0 theythenv pass out through the eduction-pipell to the motor-'or other' suitable point.

tion-chamber l, I provide an electric igniter in the following manner: In the lower end of the injection-tip 5 are screwed the plugs12, and through each of'these plugs l re inserted adjustable insulated- ,electrodes which are'slightly separated -at their inner ends, where'a spark may bel produced yat the IOO e and 1i,

instant the. .contact is made at the switch To ignite the first charge in the combuswhich completes the Acircuitthroughfthe ele@ trodes 14, thence through a 'suitable electric battery through. the switch,'then through a suitabje spark-coil to the other electrode 13, producing aspark at the inner ends of the electrodes 13 and 14, thus igniting thecharge, after which the current is cut 0E, since'from this time on the ignition will be' continuous. 'Leading to the tip5, vfrom one side thereof, is asuitable flame-arrester v15, located' in the pipe 16, and said pipe is made largerat this point in order/to properly accommodate said arrester and not to impede the flow of air and gases therethrough.

From the foregoing description the operaahand-pump may be usedto start the genera-uv tor or a pressure of airv and oil-vapors or'gases may be stored in any suitable tank or holder. In the latter case upon opening thevalve controlling the' flow from the tank .to the pipe 16 and operating at the same time: the electric switch to cause a spark to take place at'the' innerends of the electrodes 13 and 14 said-'- charge will be ignited 'and passed into thev combustion-chamber 1, thus creating a pressure which `will at once be indicated upon the gage D,'and atthe same time or any time thereafter the motor may be started, thus op erating the air and vapor compressor E and also the Water-pump F, which furnishes the Water to generate the steam in the coils that line the' combustion-chamber. The genera'- tor and motor are now considered under way and the pressure tank or holde may be cut olf, permitting the governor G to take care of the motor, as said governor contt als both the air and vaporvalves and also the water-valve; but if there be no governor these Valves may be controlled by, hand.

The vexhaust of the motor is used to pass through a suitable heating-drum H, in which proper coils are arranged for the heating of the water and also the air and vapors. Thus it will be seen that nearly all heat generated is made to do duty and that very little is thrown away.

It will also be noticed that I provide the generator with a safety Valve I to guard against accidents should the pressure pass a safe limit. The outer surfa'ceof the generator is provided with a suitable non-conducting covering or jacket J to prevent ra'diation or loss of heat.

I do not wish-to be limited to the exact construction here shown, as it will be seen that various changes in the form, proportion, and the minor details of construction may be resorted towithout departing from the princif ple .or sacrificing any of the 4advantages of this invention.'

Having thus fully described my invention, what I claim as newand useful is- 1. In combination with an internal-pressure generator having a combustion-chamber 1 and amixing-chamber 3 connected bya passage 2, the combustion-chamber -1 having its bottom, sides and top lined with a'steam-generati'ng pipe- 4, coiling to cover the bottom,

then the/sides, then the top, after which said 'pipe 4 continues to coil and form a series of pending flat coils 6 6 6, after which said pipe 4 turns. upward and passes through the opening in -the center of said coils 6 6 6 up through passage 2, into the mixing-chamber 3, through bracket 7, and secured inplace by nut 8, substantially as described.

2'; In the combination internal-com-- bustion generator, a vcombunion-chamber 1 and a "mixing-chamber 3, the combustionchainber lined with a steam-.generating pipe 4 lining the inner walls, bottomA and top in coils,'and a series of dat coils 6 6 6 suspended in the upper en'd of said combustion-chamber 1, and said pipe 4, then turns upward and `passes through the center of said flat Acoils 6v 6 6 and th rough the passage 2 into the lower end of the mixing-chamber', an induction gas and air pipe 16, furnished with'a tip 5, that passes through the bottom of the combustionchamber 1, said tip r5 being provided with a plug 12, screwedvin its lower end, said plug also provided with adjustable insulated electrodesf 13 andl v14 passing through each side and'separated from eachother slightly at the inner ends, substantially .as described. l p

' 3. A'generator of the character described,

consisting of a suitable'casing'djvided into two'compartments, one serving 'as a @0m-v bustion-chamber, and the 'other as a mixing-chamber, a coil of pipe arrang( .d within the combustion-chamber for gener: 'ning the steam, means 'for ejecting said ,Within the mixing-chamber, means for supplying the combustion-chamber with combustible gases, and means for igniting the same, as specified.

4. In combination a generator consisting of a casing divided into two compartments, one

serving as a combustion-chamber and the other as a mixing-chamber, a coil in the combustion-chamber, a motor connected with the mixing-chamber,a pump and a compressor 'operated by said motor, a tank, an escape-pipe connecting said tank with the motor, and

pipes running from the compressor and pump through the tank to the combustionechamber and coil respectively, substantially as set forth.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
